The entire mp plitte 23 is previdlecl; with ith extend applied, the some not being shown to avoid the confusion of unnecessary lines in the drawing.

Projecting inwardly from the annular flange 27 are the lugs 29, while corresponding spots 30 are provided on the lower wall 15, the bolts 31 passing through these companion lugs and binding the lower shell and the cap plate rigidly together and forming the circular mixing chamber 32 between the flanges 17 and 27 and the lower wall 15 and the division plate 33, the latter resting on the lower. shell at the intersection of flanges 17 and 18.

The foregoing construction also forms an unobstructed continuous circular distributing chamber 34 between the flanges 25-and 97 and thedivision plate 33and cap plate 23 for the purpose of eliminating all circular movement of the air and gases immediately below the cap plate so that the flame will burn evenly from all orifices Bat along the entire circular face of the cap plate 23.

\Vhen the flanges and 27 are placed between the respective flanges 26 and 28 they are preferably set in asbestos or other fire proof paste before tightening the bolts 31 so that the chambers 32 and 31 will be closed to the outer atmosphere and allow no gas or air to escape after entering the injecting tube 20 until reaehing the orifices 24.

The division plate 33 is provided with the holes'35 so that the air and gases after becoming mixed in the chamber 3-2 will pass through the holes in a straight upward movement and there will be no circular or agitating movement of the air and gases after entering the chamber 3i.

Between the annular flanges 1G and 27 and upon the lower wall 15 .ot the lower shell is formed the. generating chamber 36 for the reception of oil or any suitable combustible material for the purpose of generating gas from oil in the pipe 37, the latter beginning at the cut oil valve 38 and continuing to the boss 39 integral with the flange 16 and running upward; through the boss and then coiling over the chamber and connecting to the cross pipe fitting 40, the valve 41 connecting to the cross. and to the rectangular end 22 ot the injecting pipe 20;

by thescrews 42 passing through the flange 43 integral with the valve and into the pipe.

' 'lhe. regulating valve 41 as shown is the subject of a separateapplication for Letters Patent filed subsequent to this ,application and therefore is. not full illustrated or described herein, it is obvious however that the operation of the burner is not restricted to the employment of this particular form J of valve.

The valve 41 iscontrolled by the lever 4 and the. discharge end 45 of the valve extends sulliciently into the pipe 20 so that when gas is. admitted through the valve air Hdiameter of the ca plate flibientl 'ector and forcing the air and gas into and throughout the length of the chamber 32 and maintaining a pressure within the chamber.

Pivoted at 46 to the end 22 of the injector pipe 20 is the air regulating damper 47 with the integral arm 48 extending therefrom, the screw &9 being screw threaded into the boss 50 and positioned to open and close the damper by turning the screw to and fro.

In operation the trough 36. is sup lied with oil which is ignited and the flame t eret'rom burning upward and around the pipe 37 and vaporizing the oil therein and forming a gas.

When the oil in the pipe 37 is sutliciently vaporized the valve 41 is opened allowing the gas to escape therefrom, and as the oil in the pipe is always under pressure, usually from gravity feed, the gas will issue from the discharge end lo of the valve with considerable force and rapidity expanding and filling the injecting tube 20 and drawing air through the end 2:2 of the tube and the air and gas are intermingled and associated by the rapid injection through 'the tube 20, the

mixed air and gas traversing and filling the chamber 34, the chamber being circular causing the gas and air to flow continuously entirely and re iea-tcdly throughout the circlunterenee o the chamber and completely mixing the gas and air.

The division plate allows the mixed gases to flow through the holes 35 in a verti cal direction as a right angle to the direction of circular movement in the chamber :13 and thereby prevents this circular movement in the chamber EH so that the combustiblc gases will flow to and through the orifices 2* in a steady upward How and burn in a steady blue flame, the mixture being so perfect and the flow 0t gases through the orifices s0 steady that a blue flame will rise uniformly, from the cap plate 23 to a height nearly equal to the 38 and &1 are su opened damper 47 properly regu ated.

The foregoing construction also allows and the when the valves.

of regulating the valve -11 to a small 0' ening and th damper 47 to a correspon mg opening so that a. ver small flame will burn evenly from the ori ces 24, the burner being adapted to any degree of regulation from the smallest tothe largest flame and thereby filling all the requirements of an oil burnerfor cooking stoves, heating stoves, furnaces and the like.

'While I have herein described a pre-. ferred form of my invention, it is nevertheless to be understood that, in practising the iao - tributing chamber at a invention, I may resort to such changes and modifications as fall within the appended claims. I

at I claim as new, by tters Patent, is:-

1. A burner having an annular distributing chamber of uniform cross-sectional area, means to feed carbureted gas into said distangent whereby the gas flows continuously in one direction, and a baflle dividin said chamber into upper and lower an ar passages.

2. A burner having a continuous distributing chamber of uniform cross-sectional area, means to feed carbureted gas into said distributing chamber in a line with the ath of flow therethrough whereby iibws continuousl in one direction, dividing said chamber into upper and lower continuous passages.

3. An oil burner having an annular distributing chamber of uniform cross-sectional area, as generating means to deliver to said distri uting chamber at a tangent whereby the gas flows continuously in one direction, a baflle div'ding said chamber into upper and lower annu ar passages, and means for supplying an oxygenated gas to the burner. burner having a continuous annular chamber of uniform crosssectional area, a perforated baflie dividing said chamber into upper and lower portions, and means to feed carbureted gas into said lower portion in a line with the path of flow therethrough and desire to secure the gas whereby the flow of gas is continuous in one direction. a

5. A burner head comprising a ring like chamber having a starting trough arranged Within the ring opening below the zone of combustion, and a retort arranged vertically and a baiiie ,b

over said starting trough and continuous throughout the length of the latter, and means connecting the retort and'burner'ring to feed gas into the latter at a tangent. 6. A urner head comprising an annular channel of U-shaped cross-sectlon provided with a laterally extending peripheral flange, and an inverted annul shaped cross-section having one edge resting on said laterally extending flange and first mentloned channel to form a closed distributing chamber and a concentric startin trough.

A burner head comprising an annular channel provided with a laterally extending peripheral flange, an inverted channel memer of annular form having one on said flange and the other edge seated within the bend of the first mentioned channel to form a closed distributing chamber and a concentric starting trough.

ar member of U'- edge resting so the other edge seated within the bend of the 8. A burner head comprising a channel provided with a laterally extendi-ng fiange',

an inverted channel member having'one edge resting on said laterall extending flange and the other edge seate within the bend of the first named channel to form a closed distributin chamber and a starting trough. y

9. A burner head comprising a channel provided with a laterally extending flange, an inverted channel member having one edge resting on said laterally extending flange and the other ed e seated within the bend of the first named channel to form a closed distributing chamber and a starting trough, and a bafile dividin the said. chamber and supported on said flange.
